Philip Dunne: The hon. Gentleman is right to point out that we have some world-leading out-patient outcomes for congenital heart disease, and I recognise the statistics that he read out. This is being driven entirely by seeking to improve patient outcomes across the country—improving them even on that very good performance—and to ensure greater resilience of service in some areas where there are relatively low volumes and an over-reliance on locums. I accept that that is not the case at the Royal Brompton, but it is in some of the others.
